I was a Dropbox subscriber for over 6 years. However, I stopped paying once they stopped supporting Btrfs and XFS... the two FS I use on most of my machines. I still have a basic account on a Mac and iOS but I don't use it much and I have moved my most important data somewhere else. I know there are hacks to make it work with other FS but I can't trust hacks with my data.
